Abstract
The study evaluated the effect of adsorption with activated carbon (AC) and drying via spray drying (SD) or freeze drying (FD) on the physicochemical and functional properties of jellyfish collagen peptide powders (JCP). SD powders were drier, smaller, more uniform with extended shelf life than FD powders. Specifically, SD powders had a particle size range of 2.23–2.81 µm, lower moisture content (4.95% vs. 8.27% for FD), and longer shelf life (732 days for SD vs. 524 days for FD).
Highlights
- The effect of activated carbon (AC) on jellyfish collagen powders was assessed.
- The effect of spray and freeze drying on jellyfish collagen powders was evaluated.
- Spray drying produced drier, smaller, and uniform powders with extended shelf life.
- Freeze drying required more 130.5x energy to produce powders than spray drying.
- High-quality jellyfish collagen powders can be produced via AC and spray drying.
AC-treated powders showed lower ash content and higher protein and thermal stability than non-AC treated powders. AC-treated powders showed increased water dissolution times. JCP produced via SD required less energy (537.55 kJ/kg) than FD (70,136 kJ/kg). Powder characterization using thermogravimetric analysis (TGA) and Fourier-transform infrared spectroscopy (FTIR) showed that SD preserved peptide structure and enhanced thermal stability.
Additionally, AC-treated powders produced via SD exhibited higher surface areas and pore volumes than the rest of treatments. SD powder particles were more spherical and denser; meanwhile FD powders were irregular shaped flakes. These findings suggest that SD, combined with AC, is an energy-efficient and scalable method for producing jellyfish collagen powders with enhanced functional, thermal, and storage properties for food and nutraceutical applications.
